CURTAIN-RING.

SPECIFICATION'forming part of Letters Patent No. 279,585 dated June 19,1883.

' Application filed April 16, 1883. (No model.)

To all wh'om it may concern Be it known that I, DANIEL D. NUGENT, ofNewark, Essex county, New Jersey, have invented Improvements intheManufacture of Metal Rings for Curtains and other Purposes; and I dohereby declare that the following is afull, clear, and correctdescription of my invention, reference being had to the accompanyingdrawings, making part of this specification, and to the letters ofreferencemarked thereon, in which- Figure 1 is a view of the metal drawninto the tubular form. Fig. 2 is aview of the same rolled into thespiral form. Fig. 3 is a view of one of the rings cut from this spiralform or body. Fig. 4 is a View of, the ring with its ends beveled orinclined, as described hereinafter; Fig. 5, a View of the completed ringafter the ends have been brought together and fastened by means of thepin or rivet provided with'a small ring.

In the drawings like parts of the invention are pointed out by the sameletters of reference.

The nature of the present invention consists in improvements, as more.fully hereinafter set forth, in the manufacture of metal rings forcurtains and other purposes, the object of the invention being theproduction of rings expeditiously and at a low cost to the consumer.

Heretofore these rings have been made by employing a solid or brazedtube filled with sand or some like material, so that as the rings areformed upon a mandrel of the proper size for the purpose the tube shallnot buckle or lose its form during the operation, after which the ringsare sawed apart, the sand is emptied out, and the joint is brazed orhand-soldered; or they have been made by sinking the two parts in a dieand then soldering or spinning the two parts together 5 or a singleshell is made of a depth equal to half the diameter of the ring, and isthen closed over with adie. In the patent granted William T. MersereauAugust 5, 1879, No. 218,128, the process described is the one followedby me in the manufacture of curtain-rings, with this exception: In thecase of a ring made in accordance with that patent he ring is submittedto the heating process and its ends are soldered together. The effect ofthe heat is apartial discoloring of the metal of which the ring isformed, and the joint is not so strong or reliable as in the case of theriveting process pursued by me, attended with no risk of marring theappearance of the ring,

while the cost is not materially increased and abetter article results.A final advantage resulting from the mode of uniting the ends is thatalighter material can be availed of in the manufacture of the rings, asthey are not subjected to the action of heat.

To enable those skilled in the arts to make and use my invention, Iwilldescribe the same.

I first form from sheet metal, by drawing the same, the oval tubularstrip shown in Fig. 1, and marked A. This oval tubular strip is then runthrough grooved shaping rollers, and is bent into the spiral form B, asshown in Fig. 2. A sufficient amount of the same to form a ring is thensawed off, or separated in any convenient way, as shown at C, Fig. 3.The ends of the ring thus formed are beveled, or formed with theinclined sides, as shown at Fig. 4, and these inclined ends are broughttogether and overlap and are united by means of the pin or rivet, asshown at D, Fig. 5. The pin or rivet D is passed through openings in thelined ends of the ring and flattened on its under side, thus forming asecure and tight connection be tween the ends of the ring. Forconvenience in attaching the curtain or article to be suspended the pinD may be formed with a small ring, (1.

Having now set forth my invention and stated the advantages resultingfrom its use, I claim as new The within-described process for themanufacture of metal rings, consisting of first drawing the metal intoan oval tubular form, then bending the same into a spiral form,separating from the same the metal to form the ring, beveling the endsof the ring, and uniting and binding them together by means of a pin orrivet, D, substantially as and for the purposes fully set forth.
